It is fucking ridiculous. Unintentionally hilarious at every step. Plot holes as big as a cat's face.

And suddenly it is totally brilliant, so long as you can switch your brain off. Everyone's getting off with each other, getting killed (but not really), turning heel, turning face. The best thing is everyone kinda forgetting that they have super powers at inopportune moments, and no attempt being made to explain why they don't just turn back time whenever anything bad happens and get eveything sorted out.
